Happy New Year! In this lesson, we explore the circulatory system and more of the the awesome heart! Topics include cardiac MRI versus cardiac CT in imaging of circulatory system diseases and patient care, types of cardiac MRI, and pros and cons of MRI versus CT.

Circulatory System: Chest Pain in Coronary Artery Disease vs Stable Angina vs Unstable Angina vs NSTEMI vs STEMI

In this article, we discuss Management for Coronary Artery Disease and Differentiating between Asymptomatic Coronary Artery Disease vs Stable Angina vs Unstable Angina vs NSTEMI vs STEMI. We share a table for similarities and differences and flow chart for management of coronary artery disease. We cover stress tests and medications for coronary artery disease. Enjoy!

Cardiac Arrhythmias: Definition, Types, Symptoms, and Prevention

The heart’s function is to consistently move the blood in the body for the blood to spread nutrients to other body parts or to be replenished with oxygen and nutrients from other respective organs. The heartbeat is a way to understand the pace at which the blood is moving and how quick the heart is pumping itself. A heartbeat changes based on its environment. Running and high-intensity movement causes the heart to increase its number of beats whereas resting may lead to a lower heartbeat for the low amount activity that does not require as much oxygen. Depending on the difficulty and intensity of each activity, the heart accommodates via changing its pace to fit the body’s needs. In certain cases, however, a cardiac arrhythmia occurs and can lead to different cardiac issues that may or may not be harmless. Cardiac arrhythmia has affected millions of people in a multitude of forms. This article explains the basics of this condition such as heart block and bradycardia.
